Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a magnetic grinding equipment. Background Art

[0002] Automobile spokes are an important part that connects the wheel rim and the hub. During the spoke production process, the round cakes used to make the spokes usually need to be polished before they can be transferred to the next process due to the many pits on the surface of the head and tail materials and scratches in the previous process, so as not to affect the quality of the finished spokes. Due to the special shape of the spoke round cake material and the need to polish the entire surface of the spoke round cake material, it is difficult for existing automatic polishing equipment to fix the spoke round cake material for polishing. Even if it can be fixed, loading and unloading is inconvenient. Manual polishing is not only inefficient, but also labor-intensive and has a poor working environment for workers.

[0033] like Figure 1-12 As shown, the utility model discloses a magnetic grinding device, which includes a rotating component 1, a grinding component 2, a transverse movement component 3 and a pushing member 4.

[0034] The rotary assembly 1 includes a turntable 12, a rotating shaft 11, an electromagnet 13, a conductive slip ring 14 and a brake motor 15. The turntable 12 is fixedly arranged at the end of the rotating shaft 11 to support the workpiece 6. The electromagnet 13 is embedded inside the turntable 12. The electromagnet 13 can adsorb and fix the workpiece 6 when energized. The conductive slip ring 14 is sleeved on the outer side of the rotating shaft 11 and is electrically connected to the electromagnet 13. When rotating with the rotating shaft 11, it can still transmit electrical energy to the electromagnet 13 to ensure the normal operation of the electromagnet 13. The brake motor 15 drives the connected rotating shaft 11 to control the rotation and stop of the rotating shaft 11. The rotating shaft 11 is axially vertically arranged.

[0035] The electromagnets 13 on the turntable 12 are evenly arranged along the circumference of the turntable 12. To facilitate the installation of the electromagnets 13, a magnet pad 16 is arranged parallel to the bottom of the turntable 12, and a plurality of magnet mounting holes 121 are opened on the turntable 12. The magnet pad 16 and the turntable 12 are fixed to each other. The magnet mounting holes 121 are arranged through the axial direction of the rotating shaft 11. The electromagnets 13 are embedded in the magnet mounting holes 121 and are fixedly connected to the magnet pad 16. The magnet pad 16 can provide a stable reference to level each electromagnet 13 so as to evenly adsorb the workpiece 6.

[0036] A positioning plate 18 is provided on the top of the turntable 12. The positioning plate 18 is provided at the center of the turntable 12 and has a circular cross section. The size of the positioning plate 18 matches the center hole of the spoke round cake material, and the spoke round cake material can be quickly positioned when loading. A plurality of U-shaped openings 122 are provided at the edge of the turntable 12. The U-shaped openings 122 are evenly and spacedly arranged along the circumference of the turntable 12, so as to facilitate the grabbing of the workpiece 6 after the turntable 12 stops.

[0037] In addition, the rotary assembly 1 also includes a rotary shaft seat 17 that supports the rotary shaft 11 and ensures the stable operation of the rotary shaft 11. A plurality of bearings 171 are installed inside the rotary shaft seat 17, and pressure covers 172 are provided on both the upper and lower sides.

[0038] The grinding assembly 2 includes a frame 21, a driving wheel 22, a grinding wheel 23, a sanding belt 24 and a grinding motor 25. The grinding wheel 23 is rotatably arranged on the frame 21 and is located above the turntable 12. The grinding motor 25 is fixedly connected to the frame 21 and is drivingly connected to the driving wheel 22. The sanding belt 24 is sleeved on the outside of the grinding wheel 23 and the driving wheel 22. In this embodiment, the frame 21 includes a bottom plate 211 and a side fixing plate 212.

The traverse driving member 32 drives the traverse platform 31 to move horizontally. The traverse driving member 32 uses a ball screw slide, and linear slides 33 are arranged on both sides. The linear slides 33 are slidably connected to the traverse platform 31 along the driving direction of the traverse driving member 32. Under the driving guidance of the traverse driving member 32 and the linear slides 33 on both sides, the traverse platform 31 can drive the grinding assembly 2 to move smoothly and switch the grinding position.

[0041] In addition, the transverse movement component 3 is also provided with an accordion protective cover 34, which covers the outer side of the transverse movement drive member 32 and is fixedly connected to the transverse movement platform 31. The telescopic direction of the accordion protective cover 34 is consistent with the driving direction of the transverse movement drive member 32, and can be telescopically changed with the movement of the transverse movement platform 31, so as to protect the transverse movement drive member 32 at all times and prevent the transverse movement drive member 32 from being affected by dust and grinding debris. In addition to the accordion protective cover 34, the grinding device is also provided with a plurality of protective plates 5, each of which is vertically arranged on the side of the turntable 12, and can also block grinding debris and play a protective role.

[0042] The pusher 4 is arranged on the side of the transverse platform 31, and is respectively hinged to the transverse platform 31 and the bottom plate 211 in the frame 21. The pusher 4 can push the frame 21 to rotate around the position where it is hinged to the transverse platform 31, thereby adjusting the position of the grinding wheel 23, controlling the sanding belt 24 at the grinding wheel 23 to approach the workpiece 6 for grinding or to avoid the workpiece 6, providing sufficient operating space for loading and unloading, and improving the convenience of loading and unloading. Preferably, the pusher 4 and the tensioning drive 28 are both cylinders.

[0043] Take the grinding wheel 23-spoke round cake material as an example. Fig.13 As shown, the workpiece 6, i.e., the spoke round cake material, can be directly placed on the top of the turntable 12 and fixed by the electromagnet 13. After being fixed, the turntable 12 can be driven by the brake motor 15 to drive the spoke round cake material to rotate, and at the same time, the grinding wheel 23 can be driven by the pusher 4 to approach the upper surface of the spoke round cake material, and the grinding motor 25 drives the sand belt 24 to grind the upper surface of the spoke round cake material. During grinding, the grinding assembly 2 can be driven by the traverse assembly 3 to move horizontally to change the grinding position until the upper surface of the spoke round cake material is polished. After the grinding is completed, the pusher 4 drives the grinding wheel 23 to avoid, and the spoke round cake material can be directly removed.

[0044] In summary, the grinding device uses magnetic attraction to fix the workpiece 6. When fixing the workpiece 6, the shape of the workpiece 6 is less restricted. Therefore, the grinding device can be applied to plate-shaped workpieces 6, especially to the automatic grinding of spoke round cake materials. The device has sufficient operating space when loading and unloading materials, and the loading and unloading operations are convenient.
